Nowty Towers Vs UK Grid Storage

[Stinsy]

I'm liking the solution! You really need a CCTV camera so that you can remotely monitor water levels in the pond too!

That roof is horrendously built! "Flat" roofs aren't supposed to be completely level, they're supposed to have a 1:80 drop to a gutter, therefore water shouldn't pool at all!

Loving the ingenious ideas you guys keep on coming up with.
Wifi control is just excellent.

Could you replace drain hose with garden hose? appreciate its smaller diameter so will need a bit of bodging on, but should be uv resistant and be longer lasting

I’m probably going to try something like that, in fact I want to run the pipe along the flat roof under the tiles and then have it drain over the dormer on the same side of the roof rather than have it over the ridge tiles as the other roof side fronts the road. It’s just that the washing machine drain hose fits the pump perfectly and I could get another one locally for £7 from Screwfix.

What about a LD12 - Water/Flood Detector located at the right height so the pump suction is submerged. Use the vault free signal and a timer to switch the power supply for the pump to run and stop when the contacts go open?

No need to monitor the weather.

Bear in mind I’m not very ica so my choice of terms might not be correct but you will get the gist.

The problem is the depth is a very low depth, 10mm to 15mm and the pump will get it down to about 5mm which pretty much clears circa 90% of the water off the roof. I have thought about an automatic bilge pump which has a float switch, but some I looked at a few years back don't work reliably at very low depths, they need 40mm or 50mm.

But I’ve just read that some newer models actually run for 1 second every few minutes and if dry (no motor resistance), they stop. That could be the answer, I will have to investigate a little more.

The LD 12 would work in that depth just mount vertically 5mm above the roof level and when the water connects horizontally across the spades the pump will run. Maybe worth checking some chandlers pages for boat sump pumps too as you say theyve developed over the years- of course if you want a totally dry roof take a look at peristaltic pumps, they will self prime the suction leg and can be mounted in a convenient place and the suction tube will bring the water level down to around 0.1mm or so depending how you mount it - they wont syphon though so they would have to run for the duration but they can run un-primed without problem, depends on how dry you want the roof.

Nice day earlier but a tad windy on my mum’s roof.

I’ve moved the drain hose so it now drains on the dormer side so it’s less noticeable. Also finished re-sealing up the perished and cracked sealant where the water was probably getting in.







Should be OK for another couple of years.


My mum has a nice south facing roof but is not interested in having solar on it.

Leccy import is rising as heat demand increases and solar yields fall. Import has exceeded export in kWh's, first time since March.
But because of the 7p import and 15p export craziness, the export credit is still above the import costs.

Ripple savings and free power hours also help too.

We are about a month past the tipping point for export/import profit. The addition of No1's EV slammed the door on a finely balanced act.Leaving the discharge rate at 30% now with a 2pm blast to a higher rate is getting it done and earning a little on the export side. The Oct bill will when it arrives at start of Nov be the first that starts depleting the VB since March.
I'm ok with that as we're doing better than expected. 8 months self funded RE for this far North?

My VB took a bit of a spanking today as Octopus has finally got my account up to date from the 1st January to 24th October used £1000.65 of electricity.
Still ahead with export at £1290.61 but now going in to the higher consumption months as the temperatures drop.

Todays job is hanging off the roof, clearing out the gutter and cleaning some of the lichen off the panels.


Can't cope with the losses.
